what should i get, evolve or dying light?

No! keep the Evolve

I've been playing Evolve for like 8 hours, and yes, it's good. If you're looking for a multiplayer game take Evolve. Otherwise go for Dying Light. BTW DL will probably require a very good rig.

I'd personally go with Dying Light. I didnt like Evolve... it has a slow gameplay compared to other coop games out there.

two different games, if You like Single Player games take Dying light if Multi Player/co-op then take Evolve.
I would take DL but it's just me :P

gta 5 maybe?

As Elrash said, 2 complete different games...

I feel like Dying Light is overhyped, unless you're looking for a single player experience you should keep your copy till the release of DL (in about a month) and see if it's any good.
In the meantime Turtle Rock will probably release a new beta test.

I played the Evolve beta and it was pretty great. I'm sure the game itself will be better, with all the extra content and whatnot. If you're looking for a MP game, keep Evolve.

If you enjoyed Dead Island and want another game that's similar, or you're looking for a co-op game to play with friends, go for Dying Light. It looks like an improved Dead Island, with an added Mirror's Edge-esque touch.
